Running the central/peripheral ISO samples on the NRF52840DK

Question

Hello, 
 Using nRFConnect 2.1.0 
 I am trying to build the peripheral_iso zephyr sample, for the nRF52840 DK 
 It compiles fine as is (with the original board qemu_cortex_m3 ). 
 Now I have created another build config using the nRF52840 DK NRF52840 
 Do you know if this sample cannot be adapted for my DK ? 
 
 I tried to satisfy the config dependencies, but always fall on configs that cannot be set (not editable) like BT_CONN - CONFIG_BT_CONN 
 Nota : even if I set CONFIG_BT_ISO_TX_MTU, the build fails the same way. 
 
 Also tried some .config winmerge between the working and non working one, but there are so many CONFIG_BT that I am not surprised that it does not work. 
 I don't even find in the working build log config files listed , like qemu_cortex_m3 board specific config files (defcong + extra_kconfig_options) anything related to BT. 
 all these many BT configs seem to be auto generated 
 
 a ninja guiconfig shows a lot of red but I don't know what to think of it. I see BT_ISO in red. 
 
 here is the build log
